Description
コーティングステーションによって金属ストリップの表面を湿式コーティングで被覆するステップと、
金属ストリップ搬送装置によって金属ストリップを搬送するステップと、
湿式コーティングで被覆された表面を、この表面の一部を含む検出領域の熱画像を生成することにより、検出するステップと
を含む。
ストリップの位置の熱画像が記録されていること、
輪郭に沿って測定された温度の変化dTが確認されていること、及び
基準値に対する変化dTが、湿式コーティングの厚さの確認のために、調整テーブルとの比較のための比較値として使用されること
がさらに提供される。
図2aは、前回の洗浄及びすすぎ作業の湿気が残った、部分的に湿っている通過する仮付け溶接部を示す。湿式ローラを元へ戻した後で、均一なコーティングが再開される。しかしながら、図2bが示すように、左側の縁部領域には湿式コーティングによって湿っていない領域(A)が図示されており、又は認めることができる。表示される熱画像では、湿式コーティング及び乾燥領域の両方に同じスケールが使用されるので、異なる放射率の結果として、湿っていない領域が冷たい方の領域として表示される。それにもかかわらず、実際の温度が同一であるので、このことは単なる表示の問題である。しかし、本明細書では実際の温度は明確に決定可能でなく、要求もされてもいるわけでもないので、代わりに、湿っていない領域の確認のために、説明したように熱画像によって検出が実施される。さらなる表示である、図c)では、厚い方の領域として表示される温度スポットは、丸で囲まれた領域に見られる。表示されたこのスポットは、コーティングの厚さの不規則性を定性的に示す。図d)の表示は、湿った残渣を示し、これはより低い温度の領域として表示される。
